Auto Bandswitching Module for ICOM IC-2KL, IC-4kl and PW1 Amplifiers

Ed JohnsonEd Johnson Member ✭✭
edited April 11 in SmartSDR for Windows
I have developed an interface module that allows a Flex 6000 series to have fully automatic band switching with the IC-2KL, the IC-4KL and the PW1 Amplifiers.  It is plug in compatible with the IC-4KL and the PW-1 and provides wires to connect to the 24 pin molex on the IC-2KL. Purely a hardware box with no special software needed.  Looking to see if there is any interest in an amateur model for sale.

    Steve, putting the BOM together to establish some pricing. I have the breadboard working on my 4KL.  I am ordering pc boards and will have a few built next week.  You can reach me at [email protected]  I will keep you posted. 73 Ed

    Update..
    I have the Autobandswitcher working on the 2kl and 4kl and the code completed for the PW1.  A pre-production model going out today to an evaluator for the PW1.  Once we confirm all is working correctly, we should be in production in a few weeks.  The Autobandswitcher will support all three ICOM amps.  The cables supplied for each are slightly different... software is the same.  It requires the PW1 CI-V address to be left at the default 54h with a preferred baud rate of 9600.  The product includes inhibiting band changes in the PW1 while transmitting ... one of the flaws in the PW1 firmware.  The anticipated price will be $179 and will include all needed cables.

    Update June 18
    We have just about completed testing on both the PW1 and the IC2KL/4KL for autobandswitching with the Flex 6xxx series.  I have ordered production pcb's and am machining the cases.  We should be taking orders in the next week or so.  The price will be $179 and includes all needed cables.  There will be a model for IC-2KL/4KL and another for the PW1.  The only difference is the supplied cables.  The interface box will do all three amplifier models.  Please fell free to email any questions  to [email protected]

    Update June 26
    The first production units should be available next week.  I will post here when they are ready along with a link to purchase and a link to download photos and a manual.

    Sorry for the delays.  Due to lack of response on the IC-2KL/4KL we have decided to go only with the AutoBandSwitcher for the PW1.  In doing so we have reduced the cost to $149.  We will start taking orders on our website in about a week.  We should be in full production by August 15.  I will post the web site with a link to the manual in the next few days.  Thanks again for your patience. Please direct any questions to the email below or post them here in the forum.

    We are finally ready.  Due to the quirky nature of the PW1's CIV firmware, it took some doing to get bandswitching to be reliable and to make use of the "pass through" feature.  I will supply a link over this weekend for purchasing the AutoBandSwitcher (ABS).  It comes with all cables complete and ready to connect.  If you want to make use of the "pass through" feature you will need to supply 12VDC at 1/2 amp or more to the ABS.  The ABS emulates an ICOM radio's CIV instructions allowing seamless bandswitching.

    Here is a link for the W2PH AutoBandSwitch used to connect a Flex 6xxx to an ICOM PW1 Amplifier for completely automatic band switching while supporting the "pass through" feature of the amp. It has a description and installation instructions.

    Finally, after much testing, the W2PH AutoBandSwitch is in production.  It is $149 and includes all cables to connect your Flex 6000 to an ICOM PW1.  It fully supports "pass through" mode on the PW1 and installs in less than 5 minutes.  Please see the instructions at:

    Have you looked at the TenTec Hercules ll amps for switching. several of us have them.
  • Ed JohnsonEd Johnson Member ✭✭
    edited April 2019
    Andy,
    Please answer the following:
    1) I assume you are talking about a TenTec Model 420?
    2) Do you have the 15 pin molex (remote) connector hooked up with any wires?

    Hi Ed, tnx for your reply. Yes the Herc ll is the model 420. Currently it is married to my Orion ll via the TT model 311 Band  Data Convertor  So yes the 15 pin connector comes from the 311. As you may know the 311 is no more than a bunch of inverters to change the logic level from the Oll to the reverse levels for the input of the Herc. I have the Molex part numbers for the 15 pin connector ,but they are no longer available.

    Andy,
    Here is my suggestion.  Order the FTDI cable C232HM-EDHSL-0 which you can get from digikey.  . You will want to put Molex pins on enough wires for ground and each band that fit into the 15 pin connector housing in the positions for each band as defined in the 420 manual. You will find the color codes for each wire in the Flex USB cable doc.  When you have connected the wires to the molex connector, Plug it into the usb jack on the back of the flex 6xxx. Dont forget the black wire is ground to the 420.  Once you have done this, turn on the Flex, load the SmartSDR software and go to settings menu at the top of the screen, choose USB cables... and you should see your usb cable.  Highlight it, then edit, give it a name and then  choose "bit".  You can then assign any frequency range to each wire.  You can set the wires to be active high or active low as needed.  Once you have done this , your amp should follow the Flex.  Hope this helps.

    ED, thanks for the information. That cable assembly should work fine, however the 15 pin connector housing is not available anywhere. Many of us have searched every supplier known and it seems that Molex does not mfg them any more. Should have bought more of them. Will continue to use the Herc connected to the Orion ll.
    Tnx again

    Andy, just get the molex pin removal tool and crimp new pins onto the FTDI cable ends and insert them into the old molex housing.  I would expect the mlex pins are still available...
  • Andy W3LIAndy W3LI Member ✭✭
    edited April 11
    OK Ed, just want to avoid using the existing housing if possible. I have all of the .062 pins and extraction tools.

    Burt, 
    Firstly, the 4KL must have the 10 meter option installed.  The amp was made specifically to mate with an ICOM transceiver using the 0-8VDC band voltage that must be present along with the well regulated 8VDC supply at the accessory connector of the 4KL.  You can find the band voltage required for 10 meters from numerous places online.  Supply the amp the 8vdc, the correct band voltage plus ground, and it will switch to 10 meters if the amp has the 10 meter option.
